Model predictions on the yield distributions for different reaction products and on the
collective energy of the expanding fireball as a function of break-up time, corroborated
with the experimental results on the small-angle two-particle longitudinal correlation
functions, transition energy dependence as a function of transversal momentum and
azimuthal distributions of the collective expansion, evidence in a clear way the
possibility to access different time slots in the dynamics of the fireball.
